Description
Technical Field
The utility model relates to a msw incineration flue gas purification equipment technical field, concretely relates to atomizing disk of variable droplet diameter.
Background
The flue gas after the waste incineration is usually purified by a flue gas purification device to remove acid gas in the flue gas, so that the flue gas reaches the emission standard, and secondary environmental pollution is avoided. The core component of the semidry flue gas deacidification purification device is a rotary atomizer which is driven by a motor and drives an atomizing disc of the atomizer to rotate at a high speed through an intermediate transmission device, the atomizing disc rotating at the high speed generates strong centrifugal force, and materials (such as lime slurry) in the form of suspension or emulsion are sprayed out through a nozzle of the atomizing disc so as to be atomized into fog drops with micron-sized dimensions (such as 50-150 microns). The sprayed fog drops are contacted with the flue gas to be purified, so that acidic substances in the flue gas are removed.
The existing atomizing disk generally only has one size of nozzle to work, and under the condition of fixed motor rotation speed, the distance that the fog drops sprayed out by the atomizing disk can fly to reach is single compared with the diameter of the sprayed fog drops. If the flying distance of the fog drops is too small, the fog drops can not be fully contacted with the smoke around the wall of the atomizing tower, so that the smoke can not be fully purified; if the flight distance of the fog drops is too large, the sprayed fog drops are sprayed onto the wall of the atomizing tower and form scales on the wall of the atomizing tower, so that the waste of raw materials such as lime slurry is caused, and the cleaning and maintenance cost of the atomizing tower is increased (the scaled lime slurry usually needs to be cleaned by hydrochloric acid solution and the like, and even needs to be shut down in severe cases). The size of the fog drops sprayed by the atomizing disc also has great influence on the purification of the flue gas, and the treatment effect of the flue gas can be influenced if the particle size of the sprayed fog drops is too small or too large. In addition, when the flue gas generated by burning garbage is treated by using the rotary atomizer, the content of the acid gas contained in the flue gas is dynamically changed, and in order to achieve a good flue gas treatment effect, the state of the fog drops sprayed by the atomizer is generally required to be adjusted.
